Thanks for your posting John,  you had some good tips on file system 
repair to add to my bag of tricks, but I must disagree with the statement
above.  According to my manual, as well as empirical evidence the numbers
following "-i" are a list of inodes, not a list of logical blocks.

Consider that a large file will contain many blocks, but a file will never
have more than one inode.

I am not aware of any standard tools that will go from logical block
numbers to files, though I would love to be proved wrong.
